I know you are looking for a power fc, but thought I would just throw it out there. THe AEM EMS is a much better computer.
I have a AEM stand alone. It comes with patch harness, o2 sensor, IAT sensor, MAP, sensor and a EBC. All sensors are wired in except EBC. Everything is brand new just not in the box. The sensors are wired into the patch harness. Ill do $1800 shipped.
Here is the computer that I have for sale.
AEM Series 2 EMS for 2.0L Pulsar Gti-R 1990-1994
Have a great day,
